To all whom it may concern:

. ,Be it known that I, WILLIAM'THoMAs OOI-IOLAN, a citizen of the UnitedStates, re-

" portion being made of fabric, suitable to be siding at .New Britain,in ,the county of Hartford and State of Connecticut, have inventedcertain new and useful Improve ments in Trusses, of which the followingis a specification. 5 "f 1 Myinvention relates to improvements intrusses, and the'object of. my improvement is to produce a truss that isheld in place by a belt without the use ofsprings, the belt washed, thathas few metal parts, such metal parts as are provided being removable,and the belt construction is double, comprising an inner belt thatsupports the pad and an outer belt for applying pressure, f and the padis so related to the belt structure as to be -subject to a positive andsubstantially I A g I through the openings between the 'barsf" directinward pressure. V In the accompanying drawing Figure 1 is a plan viewof a truss embodying my invention.

Fig. 2 is a similar view, on an, enlarged scale of the front portion ofthe same.

Fig. 3 is a front elevation of the'same. Fig. 4 is a similar view of theinner belt portion.

Fig. 5' is a plan view, on a still further enlarged scale, of' the padand adjacent parts.

Fig. 6 is a sectional View on the line as w is I of Fig. 3.

Fig. 7 is a plan view of the securing device for the inner belt. V 7

My improved truss consists of a duplex belt construction, comprising aninner belt 10 and an outer belt 11 superimposed on the said inner belt,and a pad 12 of special construction that is incorporated in thestructure of the inner belt 10 and positioned at.

the proper point for applying pressure to the person as the particularcase may require, such pressure when in use being applied through themedium of the outer belt 11.

- Both belts are made preferably of woven cotton fabric, suitable forbeing washed without injury, and they are heldin cooperating position bymeans of a set of loops 26 secured to the inner belt 10 and projectingoutwardly from the outer face thereof Specification of Letters Patent.-Patentgd Sept, Application filed September 21, 191%., Serial naieamo,

suitably to v the outer b61511 jslipr d therethrough; 7 1 V The innerbelt has rheovei-ap ingeha portions secured together: by a'jloop fplatel3thatis relatively flat, so as to avoid eX cessive bunching of materialat the point of connection for the'said end portionspsuch most part onlyfor the purpose of holding the ends 1n their proper relative position,as

y connection being relied upon merely for the x such as shownor ofanyother suitable form.

The loop plate 13 ismaideofisheet materialfandfcomprlses a middlecross-barf to WhiChthc'fiXepl end lfi ofthe in nertbeltlO issecured' anda pairof end bars 17, the

free endjlS of, the said belt being rove pressure, whereby a relativelysmall belt tension will suflicev for efiecting the neces sary local,inward pressure. The particular constructlon of the pad foreifectingjhis result comprises a part 24"that serves as the pad properthat projects inwardly from' a the inner face of the inner belt,10, anda part 19 that pro ects outwardly an-appre' ciable amountin the form ofa pad extension on .the outer face of the said rinner belt 10. .7 V VThusas the outer belt 11 is tightened the portion 20 that eXtends'overthe pad 12 is in positive contact with the outer part or-pad' extension19 and exerts a pressure that is directed generally inwardly, andindependently of-the adjacent body portion 21 of the e structure of theinner belt 10. r

The result described is facilitated by the use of a pair of slip loops26, positioned one on each side of and adjacent the pad 12,

as particularly shown in Fig. 5, the said slip loop 26 serving as guidesfor'the outerbelt relatively to the said pad.

The tongueless buckle 14 is removably secured to the fixed end of theouter belt 10 in some suitable manner as by means of a loop 25 engagedwith a bar 22 on the buckle 14, the overlapping ends of the loop 25being secured together by means of a button 23 and button hole.

The fixed end portion 16 of the inner belt 10 is in the form'of .a loopthat passes around the middle bar 15 of the loop plate,

as shown in Fig 2, and the free end portion 18 in its engagement withthe loop plate passes through the two openings in the loop plate 13, oneon each side of the said middle bar 15, and has a portion superimposedon the end loop portion 16 on the outer side thereof, and which in useis in contact with the outer belt 11 and pressed inwardly thereby, so ato produce a holding friction between the superimposed portions of theinner belt.

The use of the tongueless buckle l t for the outer belt permits oftighteningthe belt positively to correspond to the particular adjustmentof the elfective length of the inner belt'lO. V 1

'I claim as my invention 1. A truss comprising an inner belt forsupporting the pad, and an outer belt for applying pressure to. the saidpad, the pad flopies of this patent may be obtained for being secured tothe said inner belt, and the said outer belt being superimposed on thesaid inner belt and comprising a portionsaid outer belt beingsuperimposed on the said inner belt and comprising a locally curvedportion that passes over the said pad, the said pad comprising a partthat projects inwardly from the said inner belt and a pad extension onthe outer side of the said inner belt that is in contact with the saidlocally curved portion of the outer belt and a pair of slip loops beingmounted on the said inner belt and positioned one on each side of andadjacent to the said pad, suitably to serve as guides for the outer beltrelatively to the said pad.
